mac80211 and nla_put_flag.patch

jalla · 10-08-2007, 06:54 AM

Hi,

I am trying to install the driver 3945ABG/BG for which I need mac80211. I am trying to follow instruction in README and get the following error:

I am quite new to linux and would really like to get the wireless networking working. Appreciate any help.

anyone pls?

christophre · 10-18-2007, 03:33 AM

have you solved this?

i am having the same problem (centos 5.0, stock kernel). the same thing happens when using the kernel source tree from the kernel SRPM (since RH doesn't publish kernel-source RPMS anymore).

jalla · 10-18-2007, 03:41 AM

no, haven't solved it yet. I have both CentOS and Vista and am using Vista for the time being, unfortunately.

jalla · 10-18-2007, 03:43 AM

Just guessing: it may look like nl80211.c is missing from the source tree...

AFAIK, that's exactly what is happening, but since i'm using centos, which uses a heavily patched kernel (AFAIK), i'd prefer to use the kernel source from the distro. this leaves me kind of stuck.

i did, however, notice that RHEL 5.1 beta has a patched kernel (still just 2.6.18 as its basis) that incorporates mac80211 and iw4965, but it's supposed to be very experimental (and it looks like it too...). i just tried that and, after hours of poking and a forced installation of the hotplug functionality missing from centos (!?), i actually got something "working." i couldn't figure out how it could load the firmware microcode otherwise. anyway, it eventually crashed out and made the system think that i was holding down the "P" key, repeating "P"s into every field in my desktop on which i focused! blargh!

long story short, it doesn't look like centos and the 4965AGN play very nicely together at all.

please do respond to this thread if you (anyone!) get's it working properly.

thanks!

I downloaded the vanilla source (2.6.23.1) which has mac80211 included and built the new kernel with support for it. But I can't boot it. Get the error msg (something about ext3.ko, that it could not be loaded).
Any hints?

I got it working finally. Do these steps:

Code:

sudo rpm -Uhv http://apt.sw.be/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
sudo yum -y install dkms dkms-ipw3945 ipw3945d ipw2945-firmware
sudo reboot

If you need a WPA key for your network, you can fix it with system-config-network.

Good luck.
